After realizing that deadlifting 70lbs is killing backs, I decided against the idea of repairing a pair of 15" Fender monitors I was given. I started tearing one of them apart yesterday, and after I got out everything (insulation was nasty yellow fiber!), I was eyeing the cab... It's a tiltback type. If I were to take a skill saw and cut it basically in half (cut where the huge tweeter was), and then put the end back on, would it work as a small amp when combined with a head? The 15" speakers are ancient and will probably blow, but since it would require no outlay of cash and I'd only use it for practicing even a few months would be ok. And I have two of these, so two speakers to kill. Also secondly considered using it for a monitor after cutting down, the tiltback is awesome and I could use a monitor..but need a practice amp more. So basically, I want to cut a monitor box into, well, really 2/3 and plop a speaker into it with some mattress foam insulation. Would it work or would cutting it down kill the sound to the point of "don't bother"? I'm not looking for greatness, just passibility for a practice amp (maybe monitor).
